How to echo a php code using ob_start in another function? - wordpress

Question

I've tried to copy my php code from foreach loop using ob start but failed. Does anyone knows how to do this? I wanted to add my php code in another function like below.
foreach($kekei as $good => $goodness) {
ob_start();
$GLOBALS['myfirstbowanstart'] .= "if ( $packing_fee === 'strtolower(".$goodness['shipping_code'].")' ) {
$label = __('Shipping fee');
$cost = ".$goodness['shipping_fee'].";
}"; // put here your recursive function name
ob_get_clean();
}
// Add a custom dynamic packaging fee
add_action( 'woocommerce_cart_calculate_fees', 'add_packaging_fee', 20, 1 );
function add_packaging_fee( $cart ) {
if ( is_admin() && ! defined( 'DOING_AJAX' ) )
return;
//$domain = "woocommerce";
$packing_fee = WC()->session->get( 'the_chosen_one' ); // Dynamic packing fee
echo $GLOBALS['myfirstbowanstart'];
/*
if ( $packing_fee === 'gzeatp1' ) {
$label = __("Shipping fee");
$cost = 3.00;
} elseif ( $packing_fee === 'box' ) {
$label = __("Shipping fee");
$cost = 9.00;
}
*/
if ( isset($cost) )
$cart->add_fee( $label, $cost );
}

<?php
$GLOBALS = array("results"=>array(), "tests" => array("test1", "test2", "test3"));
$label = $cost = "";
$packing_fees = array("gzeatp1" => "3.00", "box" => "9.00", "cotton" => "12.00");
$packing_fee = "cotton"; //WC()->session->get( 'the_chosen_one' );
$kekei = array(
"first_good" => array("param1" => "value1", "shipping_code" => "gzeatp1"),
"second_good"=> array("param2" => "value2", "shipping_code" => "box"),
"third_good" => array("param3" => "value3", "shipping_code" => "cotton"),
);
$callback =
function ($shipping_code, $packing_fee) use ($cost, &$packing_fees)
{
if($packing_fee === strtolower($shipping_code)) {
$label = 'Shipping fee';
$cost = $packing_fees[$shipping_code];
$GLOBALS["results"] = array("label" => $label, "cost"=> $cost);
}
};
foreach($kekei as $good => $goodness) {
$callback($goodness['shipping_code'], $packing_fee) ;
}
// Add a custom dynamic packaging fee
//add_action( 'woocommerce_cart_calculate_fees', 'add_packaging_fee', 20, 1 );
function add_packaging_fee( $cart = "" ) {
//Disabled for testing
#if ( is_admin() && ! defined( 'DOING_AJAX' ) )
# return;
//$domain = "woocommerce";
//$packing_fee = WC()->session->get( 'the_chosen_one' ); // Dynamic packing fee
// If $label and $cost are global variables, comment out next 2 lines.
$label = $GLOBALS["results"]["label"];
$cost = $GLOBALS["results"]["cost"];
/*
if ( $packing_fee === 'gzeatp1' ) {
$label = __("Shipping fee");
$cost = 3.00;
} elseif ( $packing_fee === 'box' ) {
$label = __("Shipping fee");
$cost = 9.00;
}
*/
echo json_encode($GLOBALS);
//if ( isset($cost) )
//$cart->add_fee( $label, $cost );
}
add_packaging_fee("test");

This is the modified code merged with yours, let me know if it works,
//Added this block
$packing_fees = array("gzeatp1" => "3.00", "box" => "9.00", "cotton" => "12.00"); //This is for testing purposes
$packing_fee = WC()->session->get( 'the_chosen_one' ); // make this a global variable
$callback =
function ($shipping_code, $packing_fee) use ($cost, &$packing_fees)
{
if($packing_fee === strtolower($shipping_code)) {
$label = __('Shipping fee');
$cost = $packing_fees[$shipping_code];
$GLOBALS["myfirstbowanstart"] = array("label" => $label, "cost"=> $cost);
}
};
foreach($kekei as $good => $goodness) {
$callback($goodness['shipping_code'], $packing_fee) ;
}
/* //Removed this block
foreach($kekei as $good => $goodness) {
ob_start();
$GLOBALS['myfirstbowanstart'] .= "if ( $packing_fee === 'strtolower(".$goodness['shipping_code'].")' ) {
$label = __('Shipping fee');
$cost = ".$goodness['shipping_code'].";
}"; // put here your recursive function name
ob_get_clean();
}
*/
// Add a custom dynamic packaging fee
add_action( 'woocommerce_cart_calculate_fees', 'add_packaging_fee', 20, 1 );
function add_packaging_fee( $cart ) {
if ( is_admin() && ! defined( 'DOING_AJAX' ) )
return;
//$domain = "woocommerce";
$packing_fee = WC()->session->get( 'the_chosen_one' ); // Dynamic packing fee
//changed this line
//echo $GLOBALS['myfirstbowanstart'];
$label = $GLOBALS['myfirstbowanstart']['label'];
$cost = $GLOBALS['myfirstbowanstart']['cost'];
/*
if ( $packing_fee === 'gzeatp1' ) {
$label = __("Shipping fee");
$cost = 3.00;
} elseif ( $packing_fee === 'box' ) {
$label = __("Shipping fee");
$cost = 9.00;
}
*/
if ( isset($cost) )
$cart->add_fee( $label, $cost );
